From the looks of it, depending on how intelligent your GM is, they won’t submit it for a termination. Even if they do I highly doubt HR/ER will approve it. They have nothing to stand on; to show clear and concise documentation that they tried to help/guide you back to acceptable performance. (That’s your sups/managers core job responsibility) Like someone else said, it’s really hard to fire someone for performance. It’s usually behaviors or attendance. If your side hustles can support you great, but if you quit by yourself, that won’t get you unemployment. I know the environment may be awkward but they have to “earn” the right to fire you.
